As the number of connected vehicles increases, there is a growing need for a communication protocol that can effectively manage a large amount of data transmission while providing low latency and high reliability, and MQTT is such a protocol… The Internet of Vehicles (IoV) is a technology that allows connected vehicles to communicate with each … Read more
Introduction MQTT (Message Queuing Telemetry Transport) is a lightweight communication protocol based on the publish/subscribe model, specifically designed for low bandwidth, unreliable, or high-latency network environments. It was released by IBM in 1999 and is suitable for connecting remote devices, particularly Internet of Things (IoT) devices. MQTT provides real-time, reliable message transmission services by reducing … Read more
Recently, the term Internet of Things has become increasingly popular, and I have been closely following the development of this industry.

Author: Free and Open Lake AI What Is MQTT Used For? MQTT is a lightweight messaging protocol typically used for IoT devices that are designed to be energy-efficient and consume minimal bandwidth. The MQTT protocol runs over TCP/IP and is based on a lossless two-way publish-subscribe model, ensuring that MQTT messages are transmitted efficiently and … Read more
01 EtherCAT Bus Protocol 1 EtherCAT System Composition EtherCAT (Ethernet for Control Automation Technology) is an open architecture fieldbus system based on Ethernet, consisting of one master device and multiple slave devices. The master device uses a standard Ethernet controller, ensuring good compatibility; any computer with a network interface card and embedded devices controlled by … Read more
1 Introduction With the rapid growth of decentralized structures in manufacturing automation and process automation, the application of field buses is becoming increasingly widespread. It facilitates data transmission between digital and analog input/output modules, intelligent signal devices, and process control devices with PLCs/PCs, dispersing I/O channels to field devices located nearby as required. This reduces … Read more
Profibus-DP Communication Protocol 1. Overview PROFIBUS – DP stands for Decentralized Periphery, which is a type of computer electronic component. It features high speed and low cost, used for communication between device-level control systems and decentralized I/O. It, along with PROFIBUS-PA (Process Automation) and PROFIBUS-FMS (Fieldbus Message Specification), forms the PROFIBUS standard. 2. Basic Information … Read more
PROFIBUS Communication 1. Overview PROFIBUS is a fieldbus standard used in automation technology, promoted in 1987 by Siemens and fourteen other companies along with five research institutions. PROFIBUS stands for PROcess FIeld BUS. PROFIBUS and PROFINET, used in industrial Ethernet, are two different communication protocols. 2. Origins The history of PROFIBUS can be traced back … Read more
